IMPROVEMENT IN STEAM-.CYLINDER LUBRICATORS.

Specification forming part of Letters Patent No. 157,844, dated December 15, 1874;. applicatian filed November 7, 1874.

proved Steam-Cylinder Lubricator, of which the following is a specication:

In the accompanying drawing, Figure l represents a vertical central section ot' my improved steam-cylinder lubricator; Fig. 2, a horizontal section of the same, taken on the line w fr, Fig. l, through the lower valve part; and Fig. 3, a detail bottom view of the valve.

Similar letters of reference indicate correspondin g parts.

My invention relates to an improved lubricator for steam-cylinders, by which the oil is fed to the cylinder with great economy and in nicelygraduated quantities; and it consists in a reservoir with a central tubular stem, surrounded by a sleeve ot' the cover or tcp part, which is provided with an adjustable screw-plug, having air-channels for conveying a greater or smaller quantity of oil to the stem, orV interrupting the supply ot' oil altogether, in connection with a grooved steamacted valve and stationary bottom plug of the lubricator, so that any required quantity may be fed in. connection with the stroke of the piston.

In the drawing, A represents the valve-cup or reservoir for the lubricating material, which is screwed, by its hollow standard or stem B, to the steam-cylinder, or other steam-acted part of machinery. The reservoir A is provided with a central tubular stem, C, cast or otherwise arranged in connection with the channel of the standard B, and closed by a top or cover, D, tightly screwed to the upper rim of the reservoir. The cover D has a central tubular sleeve, D', which is extended in a downward direction, so as to be placed over the stem C, in such a manner that the bottom iiange b of the sleeve D is retained at some distance from the bottom of reservoir A,t`or1n ing between sleeve D and `stem O a narrow intermediate space, into which the oil can readily rise to its level, and be then' conducted to the top of stem G, and to an interior shoulder, a, ofthe sleeve. lerforations or channels d pass through the top D, and admit the air to the interior of the reservoir, serving `the stem, and by another aperture, e2, at suitable distance above lthe former, with the outer air. Aperture c2 is closed entirely when the end of the plug is tightly seated on the stem, but maybe partly or completely opened when the plug israised by unscrewing from the stem, so that in this manner the supply oi' oil from the sleeve to the lower openings el ofthe plug, and thence to the interior channel of the stem, may be established, diminished, and interrupted, as required, for the purpose ot' economizing the oil and feeding it only when the engine is at-work. The position of the plug may be secured bya suitable spring locking device, so as not to be changed by the vibrations of the cylinder. A centrallyperforated plug, F, is screwed into the lower part ot' standard B, and arranged with diametrical top grooves 0r channels F. A valve, F', with similar grooves at the lower side, rests on plug F, and slides in an enlarged space above the plug, in such a manner that on the entrance of the steam through the plug from the cylinder it will close the central oil-conveying channel of standard B, and interrupt thereby the iow of oil, but will drop on the return of the piston, so as to feed the oil through the grooves and plug to the inside of the cylinder.

The action of the steam in the cylinder on the valve interrupts, at each forward stroke of the piston, the flow of oil, and re-estab; lishes the same on the return stroke. Thus the lubricating material is supplied by the action of the steam without waste to the cylinder in the quantity required, according to the speed of the engine, the quantity being regulated by means of the top plug, forming thus a reliable, substantial, and economical lubrieating device for steam-engines.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. Alubricator for steam-cylinders, Svc., constructed of a cup or reservoir, A, having hollowr standard B and interior central stem C,

a cover, D, with downwardextending sleeve D' and regulating screw-plug E, and' of a grooved bottom plug, F, and steam-acted valve F', the Whole being arranged for operatin g substantially as shown and described.

2. The combination of sleeve D', provided with interior shoulder a, with central cup-stem C and screwplug E, having central channel e,with lower and upper apertures c1 e2, for the purpose of regulating and interrupting the oW of lubricating material to the cylinder,

vsubstantially as and for the purpose set forth.
